Fossils
Geologists use these to help them order rock layers
100
Crust, mantle, core
What are the layers of the geosphere?

Minerals
What makes up rocks?
100
A mineral is a solid, inorganic substance of natural origin with a defined chemical composition and a crystalline structure
Define a mineral
100
Nonrenewable
Are minerals renewable or nonrenewable?
200
Sedimentary rocks
This is the rock a geologist would usually find a fossil in.
200
the outermost and thinnest layer- composed of rocks that are solid and hard but lightweight
Define the crust layer (what it consists of)
200
Rocks
These make up earth's lithosphere BUT can range to be various sizes, even a grain of sand
200
Silicate and non-silicate
What are the two categories of minerals?
200
Ore- A mineral from which an element is extracted
Gangue- the worthless remainder of the rock it is in
Define the words "ore" and "gangue"
300
Moh's hardness scale
This scale is used to tell the hardness of a rock
300
The middle layer- consists of denser rocks and its temperature and pressure increases with depth
Define the mantle layer (what it consists of)
300
Igneous rocks
This type of rock is formed during seafloor spreading
300
Feldspar, biotite, quartz
What three minerals form granite?
300
Uraninite
What is an example of an energy mineral?
400
Streak test
This tests to see what color comes when you rub a rock against a tile.
400
The innermost layer- composed of iron and nickel
Define the core layer (what it consists of)
400
Weathering and cementation
The two things that happen for sedimentary rocks to become what they are
400
Surface colour, lustre, crystal habit, hardness, cleavage
What are the five main properties to identify minerals?
400
Quartz, halite, graphite
What are the minerals used in construction and industry?
500
